JAMES A. STEVENSON AND LEWIS O. PHILLIPS, OF NEW CASTLE, PENNSYLVANI WATER-CLOSET.

Specification of Letters Patent.

Eatented Feb. 18,- 1908.

Application filed Mat 6. 1906. semi in. 315.273.

To all whom it may concern:

Be it known that ,we, JAMES A. STEVEN- SON and LEWIS O. PHILLIPS, citizens of the United States of America, residing at New Castle, in the county of Lawrence and State act'er described, which will obviate the neonly a normal supp cessity of a storage tank for supplying additional water to the bowl to cause si honic action, and likewise rovide a means w ereby y pipe need be used; as any ordinary low pressure house supply will be sufiicient to cause our device to flush properly without the use of a' storage tank or an enlarged supply pipe.

In the accompanying drawings in two sheets forming a part of this specification we have shown several different views of our device, Figure 1 being alongitudinal section on line 11 of Fig. 2, Fig. 2 is a plan view partly in section. Fig. 3 is a rear vertical section on line 33 of Fig.- 2. Fig. 4 is a cross sectional view on line 4.4 of Fig. 3. Fig. '5 is a vertical section on line 5 '5- of Fig. 2, and Fig. 6 is a sectional view ofa portion of the rim on line 6.6 ofFig.2.

V the bowl 2 is an The lower end of the inside is the bowl 2.

- inafter more speci U shaped pi Throughout the drawings the numeral 1- indicates the body portion of the closet which is constructed in the usual manner well known to devices of this character, and on Communicating with the lower portion of inverted Ushaped ipe' 2 which forms an air trap 3, is part'of t e outlet system of our device, andis the essential feature which we emplo idea; the detailed art oi which will be herefi zcally described. The two legs of this pipe are designated by A and B. the leg B communicates through an opening 3 with'another inverted e4, havinglegs C and D respectively, WhlC to carry out ourconstitutes the remaining portion of the discharge system, and is located alongside and in close proximity to the pipe 2. The lower end of the leg D is connected at the floor line with the soil pipe, and at this point in said leg D there is arranged a widened out portion 4 ending in a shelf 4 This construction is intended for the purpose of breaking the column of waterpassing down through leg D and insure be ter siphonic action. y r

In. the rim portion 5 of the bowl there is formed a storage chamber 6 which is of any desired capacity, while adjacent thereto and separated by a partition 7, is a flushing rim 8 from which alurality' of openings 99 communicate wit the bowl 2. v

Formed in the rear portion of the rimpand separated from the storage chamber 6 by a partition 10, is an air chamber 11, through the top of which passes'an escapem'en't duct 12, one end communicating with the storagechamber 6, and the o po'site end with the rear of the bowl. This d for said storage chamber until said chamber is filled with water; also a'fiordsa means for 1 taking care of the overflow from said chamuct acts as an air relief ber and likewise admits air to prevent a vacuum in said chamber while it is emptying. Arranged in the front part of the storage chamber 6 isa goose neck communicating with a "empties into the bowl at any desired point, the free end entering a pocket or depression 16 iorm'e'd in the bottom of the chamber 6 This goose neck trap is utilized for the purpose'of holding the water iiisaid stora e chamber until needed, as will be more in y described further'on, while the free end of the air trap 14, Fig 1, passage 15, wh1ch goose neck is placed in the depression. before mentioned for the purpose of insuring the complete emptyingpf said chamber.

Arranged through the rear wall of the bowl is a drain passage 17, Fig. 1, the upper end communicating'with the air char-ber 1'1 and the lower end withthe leg A at any desired point Y Water'i's admitted from anordinary house" supplypipe 18, Fig. 3, having either high or low pressure, and is distributed simultavice: the admission of water being regulated by any suitablevalve means or fiushom'eter 19, or else controlled by hand.

0ne branch supplies :the air chamber ii n'eously to three different parts of our de-*' through a pipe 20, while another pipe 21 supplies the flushing rim 8-, andhas a branch 22 leading to the storage chamber 6.

The said supply pipe 18 enters the connection 23 at a sharp angle, in order that the flow of water will be forced to air chamber 11 and not to air trap 3 and at the same time will trap end of pipe 24 and prevent any air from escaping from the air trap 3 through the connection 24 a1id 25 during the filling process.

Leading from the connection 23 to the air trap 3 is a pipe 24, and connecting with the pipe 20 is another pipe 25 which communicates with the interior of the siphon leg Leading from the air chambjer 11, which it enterson about the same level as the supply line 20, is a pipe 26 which in turn connects with the pipe 24 and conducts the air from air chamber 11 to air trap 3 when air chamber 11 is filling with water.

The operation of our invention is as follows :VVater stands in the bowl 2to the height of the overflow point X; also in the siphon legs A, B and C at same level, these two inde endent bodies of water acting as a seal to t e air trap 3 during filling process. When Water is turned on, or admittedto a main supply pipe 18 controlled by any auto matic valve means, or by hand, it will go to the storage chamber, flushing rim and air chamber, also to the bowl in the manner heretofore described. As the water enters the air chamber 11 it compresses the air contained therein and forces the same out through the pipe '26 andinto the air trap 3; the vent 17 being much smaller than the supply opening, will allow of said chamber being nearly'fillcd with water, and the air contained therein forced into the trap 3, before siphonic action takes place and after said action the said air chamber empties itself through said duct 17 by getting an air relief from leg D through pipes 25 and 20. air being forced into the tra 3 from said chamber 11 tl'nough pipe 26 wi lbe prevented from escaping to siphon leg D by reason of the flow of water sealing the ends of the pipes 24 and 25, while said water is llowing through pipe 20' and by the seal caused by the water standing in legs A and B. The air being forccd'into the trap 3 will back up the water in the bowl, and likewise in the siphon leg C,

which, together with the water coming from the storage chamber, flushing rim and air chamber, will cause a suilicicnt head of water to be accumulated in bowl 2 above overflow point to insure proper siphonage when air is released.

When the water in the bowl fills to a sullicient height to insure siphonagc action, and overcome the air seal confined in the trap 33, the supply is shut oil either by an automatic valve, llushomcter, or else by hand. The

instant said supply is shut oil, the air con-' and in so doing traps the water in the storage chamber until the water in the bowl recedes from the end of said duct 15, when the air in trap of goose neck will escape and be fol lowed by all the water contained in said storage chamber thus assisting in thorough washing out of the bowl and also leaves a sufficient after fill ready for the next opera tion. The drip from the air chamber through duct 17 into outlet pipe 2' will also assist in after filling of bowl.
